Science Cosmology

L'Univers a-t-il une forme ? En s'intéressant au contenu visible de l'univers, aux planètes, aux étoiles et aux galaxies, on oublie parfois le contenant invisible, l'espace lui même. Celui-ci est-il un simple réceptacle passif ? A-t-il une forme, une structure ? Est-il fini ou infini ? Est-il courbe, plat, lisse ou grumeleux ?Une présentation des différents modèles cosmologiques. Jean-Pierre Luminet présente les grandes lignes des démarches cosmologiques actuelles et des formes possibles de l'univers.

Jean Pierre Luminet nous invite à un voyage fascinant qui, de la Grèce antique à nos jours, explore les métamorphoses de l'infini. De manière toujours accessible, il aborde l'infini de l'espace avec la cosmologie, celui des nombres avec les mathématiques et les mystères de l'infiniment petit dans la matière avec la physique quantique.

Highly esteemed astrophysicist Joseph Silk explores the vast mysteries and speculations of the field of cosmology in a way that balances an accessible style for the general reader and enough technical detail for advanced students and professionals. Indeed, while the physical laws and origins of the universe can be endlessly complex, even Einstein once mused that they could be explained simply enough to be grasped by nonspecialists.

Os grandes mistérios e maravilhas do céu noturno sempre nos fascinaram, intrigaram e divertiram, desde os primeiros passos na Terra. Hoje, continuamos nos esforçando para entender o nosso lugar no cosmos. O século 20 foi palco de importantes e assombrosas descobertas sobre o nosso próprio planeta, o sistema solar, as estrelas e as galáxias. Contudo, ainda buscamos respostas para inúmeras questões, e essa busca nos proporciona uma valiosa compreensão da vastidão e das infinitas possibilidades do espaço universal que ainda estamos por descobrir.

Trous noirs, exoplanètes, les nouvelles techniques d'observation en astronomie ont permis d'extraordinaires découvertes. Une résolution beaucoup plus fine des images. Durant les dernières décennies, de nouveaux instruments d'observation situés sur Terre et dans l'espace ont, grâce à des progrès dans la résolution des images, donné lieu à des découvertes extraordinaires. Trous noirs et exoplanètes : des découvertes extraordinaires. Pierre Léna décrit ici ces innovations instrumentales et s'attarde sur deux découvertes majeures récentes.

Un Univers en expansion - La cosmologie est l'étude de l'Univers dans son ensemble. En expansion depuis 15 milliards d'années, son histoire est jalonnée d'événements cosmiques : fabrication de la matière, génération du rayonnement cosmologique, apparition des galaxies... La cosmologie est aujourd'hui devenue une science, relativiste depuis le début du XX° siècle.Une histoire de nos nos connaissances sur l'Univers. Marc Lachièze-Rey retrace ici les grandes lignes de l'évolution des idées et des principes qui fondent nos connaissances sur l'Univers.

Fra tutte le teorie scientifiche, la relatività è quella che più ci affascina e ci sconcerta. Andando contro la nostra rassicurante percezione del mondo, ci costringe a prendere atto che spazio e tempo non sono due dimensioni fisse e separate, ma si contraggono e si dilatano, sfumando l'una nell'altra, fino a perdere la loro individualità. La realtà è, dunque, molto più strana di quello che appare. Tutto ciò può sembrare misterioso o comprensibile solo agli addetti ai lavori. Ma non è così.

En El universo en una caja, el profesor de cosmología Andrew Pontzen, explica de una manera clara y rigurosa qué son las simulaciones, esos códigos informáticos con los que los científicos han podido recrear el universo y profundizar en su historia, poniendo a prueba por primera vez ideas centenarias. Esta suerte de manual fundamental para amantes de la astronomía, que aún está desplegando sus capacidades, replantea lo que creemos saber sobre los agujeros negros o la materia cósmica para arrojar nuevas luces sobre nuestra realidad.

Spectroscopy, the study of the interaction between matter and electromagnetic radiation, may sound complex and esoteric, but at its heart lies a simple and profound idea: the colors of light can reveal the secrets of the universe. From the examination of distant stars to the analysis of molecules in a laboratory, spectroscopy is the key that unlocks the hidden stories encoded in light.

Seja você um entusiasta da ciência, um pensador profundo ou simplesmente alguém em busca de aventura e sabedoria, este livro promete um refúgio do cotidiano, transportando-o em uma viagem de conhecimento e inspiração.

For Irwin Shapiro, science starts with questions. This book provides a broad and entertaining survey of major scientific discoveries that have changed our views of nature and, in turn, spawned further questions. Shapiro, an award-winning scientist and beloved teacher, separates his inquiry into three parts: looking up at the universe; looking down at the earth and its fossils; and looking in at the story of life. His framework encourages listeners to view science as a detective story—to observe and question nature and natural phenomena, and to base all conclusions on scientific evidence.

An extraterrestrial colony, in some form, may already exist, just awaiting discovery. But the greatest impediment to such an important scientific discovery may not be technological, but political. No scientific endeavor can be launched without a budget, and matters of money are within the arena of politicians. Dr. Ben Bova explores some of the key players and the arguments waged in a debate of both scientific and cultural priorities.

In Into the Unknown, astrophysicist Kelsey Johnson takes us to the edge of scientific understanding about the universe: What caused the Big Bang? What happens inside black holes? Are there other dimensions? She doesn’t just celebrate what we know but rather what we don’t, and asks what it means if we never find that knowledge. Exploring the convergence of science, philosophy, and theology, Johnson argues we must reckon with possibilities—including those that may be beyond human comprehension.

Set in a revolutionary era of physics and science when a series of rapid-fire discoveries was upending our understanding of the universe, Splinters of Infinity by Mark Wolverton tells a little-known story: the tale of two of America's foremost physicists, Robert Millikan (1868-1953) and Arthur Compton (1892-1962), who found themselves locked in an intense, often deeply personal, conflict about cosmic rays.

「はじめに」より 本書で紹介する宇宙思考のポイントは、次の3つです。①宇宙において、見えるもの、そして知ることができることは、視点に依存しており、視点に限られています。

During the formative years of Egyptian civilization, each Cosmogony was present. Students from many regions and segments of society attended the Houses of Life, and royals regularly donated endowments for the temple's maintenance and activities. These circumstances suggest a theological harmony, suggesting that a group of religious centers must have been cohesive despite their distinctive teachings and practices. Regardless of time or place in popularity, each creation myth was integral to the Egyptians' worldview.

O tempo não é um conceito abstrato. É uma substância material que ocupa todo o universo e se deforma, vibra, oscila. De Newton a Einstein, de Planck ao relógio cósmico, foi protagonista de metamorfoses vertiginosas, fascinantes e monstruosas. O tempo flui? Ou está parado? E como é medido? Como a gravidade o retarda? E como os buracos negros conseguem pará-lo? Sempre vivemos no tempo, que, no entanto, não é eterno.

Vorwärts in die Vergangenheit. Weiße Löcher sind das Gegenteil von Schwarzen Löchern – sie sind vermutlich ihre Abkömmlinge. Die einen ziehen alle Materie unwiderstehlich in sich hinein, die anderen geben ihre Information wieder frei. Sie sind ein weiteres großes Rätsel der Kosmologie, und noch gibt es keinen Beweis ihrer Existenz. Einsteins Gleichungen lassen sie aber vermuten, und mit Carlo Rovellis Quantentheorie sind Weiße Löcher theoretisch darstellbar.

Forty-four science articles using the Rational Scientific Method of Inquiry. These subjects are covered in the book Curious Chain of Events, and this is the first in a series of Rational Science books.

Everywhere light goes, It has found that darkness is already there. Darkness is the natural state of the universe. For a star to be born, it takes an astounding number of possibilities to become a reality. From this unlikely alignment, we now have trillions of stars! Thankfully stars would progress to give us light, life, and an observable universe. No one knows how many stars exist, but we will tour a handful of the most famous in our known universe. Sit back and enjoy the world of outer space that spreads before you. Each constellation and luminary has a story that you won’t want to miss!
